Η εγγονή της μένει στην πόλη, αλλά μιλάει μαζί της κάθε βράδυ στο τηλέφωνο.

Greek normally uses the definite article with possessed nouns. So η εγγονή της is the standard way to say her granddaughter.

Literally, it is closer to the granddaughter of hers, but that is not how you would translate it naturally into English.

It is the same pronoun form, but it does two different jobs here:

• Η εγγονή της = her granddaughter
  Here της shows possession, so it means her.

• μαζί της = with her
  Here της goes with μαζί and means her as the person someone is with or speaking with.

So the form is the same, but the function changes depending on the phrase.

Greek often leaves out subject pronouns because the verb ending already tells you the person and number.

So μιλάει by itself means he/she/it speaks/talks.
The exact subject is understood from context.

In this sentence, English may need to say she, but Greek usually does not.

You usually know from context.

By itself, μιλάει is just he/she talks. Since Greek does not mark gender in that verb form, the sentence can be ambiguous if you read it in isolation. The surrounding context, or the meaning already provided to the learner, tells you who is doing the talking.

If a speaker wanted to make it extra clear, they could name the person again.

Here μένει means lives or resides.

The verb μένω can mean different things depending on context:

• stay
• remain
• live

In μένει στην πόλη, the natural meaning is she lives in the city.

Because στην is the contracted form of σε την.

So:

• σε την πόλη → στην πόλη
• σε το τηλέφωνο → στο τηλέφωνο

These contractions are standard and very common in Greek.

It is in the accusative singular: την πόλη.

After σε, Greek uses the accusative. So even though English says in the city, Greek structure is literally to/in the city with the accusative form.

Yes. Both μιλάει and μιλά are correct.

They are two common present-tense forms of the same verb:

• μιλάει
• μιλά

Both mean he/she talks or he/she speaks.
In everyday Greek, μιλάει is very common, and μιλά is also completely normal.

μαζί means together or with, depending on the structure.

In μαζί της, it means with her. So:

• μιλάει μαζί της = she talks with her

This is a very common way to express with someone in Greek.

Yes, but it is not exactly the same style.

• μαζί της is very natural and common for with her
• με αυτήν is also possible, but it can sound more explicit or emphatic depending on context

In this sentence, μαζί της is the most natural everyday phrasing.

It means every evening or every night, depending on context.

A few useful points:

• κάθε = each / every
• the noun after κάθε is singular
• there is no article here

So:

• κάθε βράδυ = every evening / every night

Because βράδυ covers a time span that English can divide differently.

Depending on the situation, it may be more natural in English to say:

• every evening
• every night

Both can fit κάθε βράδυ. The best choice depends on the context and the tone of the translation.

Here στο τηλέφωνο means on the phone or by phone.

Literally it is on/at the telephone, but in natural English you usually translate it as:

• on the phone
• over the phone
• by phone

So μιλάει μαζί της κάθε βράδυ στο τηλέφωνο means she talks with her every evening/night on the phone.

Because αλλά means but, and it links two clauses.

Greek punctuation here works much like English:

• Η εγγονή της μένει στην πόλη, αλλά...
• Her granddaughter lives in the city, but...

So the comma is normal and expected.

εγγονή means granddaughter.

The masculine form is:

• εγγονός = grandson

So the ending helps show gender:

• η εγγονή = the granddaughter
• ο εγγονός = the grandson

Not completely. Greek word order is more flexible than English.

This sentence uses a very natural order:

• Η εγγονή της μένει στην πόλη, αλλά μιλάει μαζί της κάθε βράδυ στο τηλέφωνο.

But Greek can often move parts around for emphasis. For example, κάθε βράδυ could be placed elsewhere without changing the basic meaning.

The chosen order here sounds neutral and natural.
